Emissions and immissions measurement
Since 1991, the Laboratory of Emission and Immission Measurements of ELVAC EKOTECHNIKA s.r.o. has been authorized for one-off measurements of pollutant emissions for the widest range of pollutants, including technological measurements. We carry out emission measurements of all industrial sources of air pollution according to customer requirements. Since 2008, the Laboratory of Emission and Immission Measurements of ELVAC EKOTECHNIKA s.r.o. has been accredited for emission measurements according to ČSN EN ISO/IEC 17 025.
The Laboratory of Emission Measurement and Immissions has continuous analyzers of gaseous pollutants (TOC, CO, SO2, NOx, N2O) and manual sampling equipment for emission measurements. It uses automated gravimetric apparatus for isokinetic sampling.
In addition to authorized emission and immission measurements, the laboratory performs various types of technological measurements, work environment measurements and consulting activities.
We are a member of the Association of Authorised Laboratories for Emission Measurement ALME and regularly participate in inter-laboratory comparison tests.
The laboratory undertakes to maintain the confidentiality of all information obtained or created during the performance of laboratory activities.

industrial operations generating emissions

Heating plants and power stations
Authorized emission measurements in heating plants and power stations are crucial for complying with applicable emission limits and ensuring operational safety. We perform comprehensive monitoring of exhaust gases, which ensures compliance with legislative requirements under the Air Protection Act. Our services include continuous and occasional measurements of CO₂, NOₓ, SO₂, and dust particles, which significantly minimizes the risk of fines and improves the environmental profile of operations.

Chemical plants
In chemical plants, emissions of gases and volatile organic compounds can vary significantly depending on the substances produced and the technologies used. Authorized emission measurements allow you to accurately identify leaks and optimize production processes. Our expertise covers the determination of a wide range of pollutants (e.g., VOCs, HCl, HF, heavy metals, and others), helping to minimize the impact on the environment and worker health.

Cement plants
Cement plants are among the largest sources of dust emissions. Authorized measurement of emissions from furnaces and mills allows for the control of dust particles and gaseous components so that operations comply with the most stringent emission standards. By working with us, you will receive a detailed report on emission balances and recommendations for optimizing operations.

Waste incinerators
In waste incinerators, it is essential to monitor emissions of volatile organic compounds, polychlorinated dioxins, furans, and other hazardous substances. Authorized emission measurements ensure that the incinerator operates in accordance with EU directives and national regulations. Our solutions include reference measurement techniques and manual sampling, which provide high accuracy and reliability of data.

Asphalt plants and concrete plants
Emissions of dust particles, organic solvents, and NOₓ are generated in asphalt plants and concrete plants. Regular authorized emission measurements help to detect inefficient exhaust paths or possible leaks. Evaluating the measured values allows you to implement more economical technologies and better filtration systems, thereby reducing costs and your carbon footprint.

Biostations and solid fuel boiler rooms
The operation of wood or pellet biomass boiler rooms requires the measurement of CO, CO₂, O₂, and dust particles. Authorized emission measurements help optimize combustion and achieve maximum efficiency. Thanks to our accreditation, we ensure that all measured values are recognized by state authorities.

Refinery
Oil and petrochemical refineries require very strict controls on emissions of SO₂, NOₓ, CO, and volatile organic compounds. Authorized emission measurements are necessary not only to comply with permits, but also to manage operational safety. Our comprehensive solutions include authorized sampling directly on site.

Paper mills
In paper mills, emissions mainly relate to sulfur dioxide and dust from pulp. Regular authorized measurements of emissions from boilers and gas or steam dryers help to keep production in line with emission standards. We propose individual measurement plans that take into account the capacity of the line and the type of material being processed.

Metalworking operations (foundries, rolling mills)
In metalworking operations, emissions of metal oxides, smoke, and dust escape during smelting, casting, and rolling. Authorized emission measurements ensure accurate determination of dust and metal element concentrations. With our services, you can easily demonstrate compliance with regulations and use the data to implement modern filtration technologies.

Frequently Asked Questions (FAQ)
Authorized emission measurement is an official, government-recognized one-time measurement of pollutant concentrations in exhaust gases/compressed air, performed according to reference methods by an accredited/authorized laboratory. It serves to demonstrate compliance with emission limits and legal obligations. We have been a laboratory authorized by the Ministry of the Environment since 1991 and accredited according to ČSN EN ISO/IEC 17025 since 2008. We have continuous analyzers (TOC, CO, SO₂, NOₓ, N₂O) and equipment for manual and isokinetic sampling.
Technological measurements are purposeful and tailored to your technology – they are used when commissioning equipment, optimizing, troubleshooting, or verifying efficiency. These are not one-time authorized measurements required by law, but practical measurements for operational decisions. We also perform these measurements and will suggest a suitable scope and methods for you.
We measure virtually all industrial sources: heating plants and power plants, chemical plants, cement plants, waste incinerators, asphalt plants and concrete plants, biostations and solid fuel boiler rooms, refineries, paper mills, and metalworking operations (foundries, rolling mills).
When you need to prove compliance with legislative requirements and emission limits set by the Air Protection Act and your operating permit. We will help you set the correct scope and timing of measurements to meet the requirements of the authorities.
The frequency is determined by legislation and the conditions of your permit (IPPC/ZOZ). Upon request, we will propose a schedule in accordance with the obligations of the specific source. (General intervals vary between sources.)
Depending on the required substances, we use continuous gas analyzers and perform manual sampling; for dust/TZL, we use isokinetic gravimetric apparatus. Sampling and analysis are performed according to reference methods (e.g., chemiluminescence, flame ionization detection, ion chromatography, AAS/ICP, etc.). The output is a report with results and evaluation against limits.
Ensure safe access to consumption points (platform/ladder), operational condition of the source in accordance with the permit, documentation on the process (fuel, output, operating parameters), connection to the electrical network for the equipment, and contact details for the responsible person.
Approximately 6 hours per source as standard; up to around 12 hours for more extensive measurements or multiple monitored parameters. Processing the report usually takes another 1–2 working days.
We usually prepare the measurement report within 1–2 business days after completing the work on site. The operator is responsible for submitting the report to the Czech Environmental Inspection Agency (ČIŽP); upon request, we can prepare all the necessary documents and advise you on how to submit them.
The price is individual—it depends on the number and type of substances measured, the scope of the campaign, the accessibility of the measurement sites, and logistics. We will provide a quick calculation after a short consultation (ekotechnika@elvac.eu, +420 724 844 378).
The amount of penalties is determined by the relevant authorities in accordance with the Air Protection Act and the conditions of the permit. If we find any non-compliance, we will propose corrective measures and appropriate technologies to reduce emissions; we can also verify their effectiveness through measurements. (We describe our general approach in our services.)
Authorized emission measurements may only be performed by a laboratory authorized by the Ministry of the Environment or accredited for the given methods and substances. ELVAC EKOTECHNIKA has all the necessary authorizations and certificates.
Yes. We perform authorized and technological measurements throughout the Czech Republic and are able to meet the requirements of EU member states.
